Plant-growth inhibitors

The early literature on naturally occurring plant growth inhibitors and the influence one plant might exert on another by chemical means (allelopathy) is considered comprehensively in various reviews (12, 15, 36, 37, 48, 49, 61, 67, 94, 121, 162). Reviews of studies concerned with the influence of plant exudates on root-infecting fungi (130) and the effects of phytotoxins which arise as decomposition products (113) have appeared recently. Because of the excellent coverage of the topics by others, no attempt is made here to review the early literature exhaustively. Instead, consideration is restricted essentially to specific compounds and to some of the more recent literature. [Pg.117]

In 1963, Fletcher and Renney (.2) detected a plant growth inhibitor in knapweed and they suggested an allelopathic role for the substance(s) that could promote the spread of knapweed. Although these results are widely quoted, the inhibitor has never been identified nor has its existence been confirmed. Twenty years later, knapweed allelopathy was reexamined in our laboratory. A series of diffuse knapweed isolates were found to be inhibitory to ryegrass germination in petri dish assays... [Pg.238]

Hence we sought to determine whether we simply were observing the effect of parasorbic acid, a known plant growth inhibitor, or its glucoside in our tests. [Pg.329]

Although the bioassay of racemic parasorbic acid showed good activity (wheat seed root growth was 50% inhibited with 0.25 mg/mL), the conclusion that little of the growth-retardant activity in cranberry leaves can be accounted for by parasorbic acid was confirmed by examination of Devlin s extract. In this case neither parasorbic acid nor its glucoside was present. Subsequent work by Hussain (12) has resulted in the isolation of two plant growth inhibitors identified as cinnamyl alcohol and 3-pheny1-1-propanol (hydrocinnamyl alcohol). [Pg.333]

The studies on the inhibitory effects of podolactones A (29) and E (51) and nagilactone E (36) were extended to a range of bioassays [73]. In some of these assays, the effects of the podolactones were compared to those of lycoricidinol and harringtonolide, plant growth inhibitors (Table... [Pg.481]

A number of naturally occurring compounds with a disulfide unit have shown interesting biological activity [28, 29]. Nereistoxin, charatoxin, asparagusic acid, a plant growth inhibitor, and lipoic acid, a key co-factor in the oxidative decarboxylation of pyruvate, are examples taken in the 1,2-dithiolan series. [Pg.11]

One of the metabolites of the trichothecene family of mycotoxins, termed "neosolanoil" (246) was isolated from Florunner peanuts and identified as 3a-hydroxy-4B, 8a-15-triacetoxy-12,13-epoxy trichothec-9-ene. This toxin was shown to be a potent plant growth inhibitor active to 10 % in the wheat coleoptile bioassay. [Pg.188]

Curry leaf has been reported to contain plant growth inhibitors. Bhattacharya et al. (1989) described the isolation and characterization of two coumarins present in M. koenigii bark. The growth-inhibitory properties are comparable to those of other coumarins, such as psoralen and xanthotoxin. [Pg.421]
